Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Different loads of inspiratory muscle training will produce different hemodynamic responses.;The loads of 30 and 60% produced different hemodynamic responses. The load of 30% generated a decrease in the systolic volume variable and the load of 60% increased cardiac output. The placebo load did not generate significant changes in any parameter. | — |
